Rick used 4-2-3 yards to sew 3-1-2 shirts what is the unit rate of cloth he used in terms of yards per shirt Mathematics 7th grade

Answers

Answer 1

Answer:

If Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts. The unit rate of cloth he used in terms of yards per shirt will be 4/3.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

The unit rate of cloth he used in terms of yards per shirt is found by dividing the 3 1/2 shirts by 4 2/3 yards,

$= 4 (2)/(3) / 3 (1)/(2) \n\n = (14)/(3) / (7)/(2) \n\n = (14)/(3) * (2)/(7) \n\n = (4)/(3)$

Thus, if Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts. The unit rate of cloth he used in terms of yards per shirt will be 4/3.

if there are 2 boards on a shelf one is 234 in the other is 246 in what is the total legth of the boards

Answers

The lengths of the two boards (234 inches and 246 inches) and adding them together, we find that the combined length of the boards is 480 inches.

To find the total length of the two boards, you need to add their individual lengths together.

Step 1: Identify the length of each board. The first board is 234 inches long, and the second board is 246 inches long.

Step 2: Add the lengths of the boards together.

234 (length of first board) + 246 (length of second board) = 480

So, the total length of the two boards on the shelf is 480 inches. This means that if you were to place the two boards end-to-end, they would cover a distance of 480 inches.

In summary, by identifying the lengths of the two boards (234 inches and 246 inches) and adding them together, we find that the combined length of the boards is 480 inches. This calculation helps us understand the total amount of space the boards would occupy if placed side by side.

Please please help!!Volcanoes prove that the Earth's center is hot. The formula T= 10d +20 is used to estimate the temperature, T degrees Celcius, at a depth of d kilometres (km).
A) what does each term on the right side of the equation represent?
B) Estimate the depth where the temperature is 60 degrees C.
C) What is the approximate temperture at a depth of 4km?

Answers

Answer:

The formula T= 10d +20

A) what does each term on the right side of the equation represent?

10d⇒ 10 degrees increase per 1 km and 20 deg surface temperature

B) Estimate the depth where the temperature is 60 degrees C.

60=10d+20
10d=40
d=4 km

C) What is the approximate temperature at a depth of 4km?

T=10*4+20
T=60 deg

A scientist suggests keeping indoor air relatively clean as follows: provide 2 or 3 pots of flowers for every 100 square feet of floor space under a ceiling of 8 ft. If your classroom has an 8 ft ceiling and measures 35 ft by 40 ft, how many pots should it have?

Answers

First we calculate classroom surface:
35*40=1400 square ft
we know that for every 100 square ft 2 or 3 pots can be put
so 1400/100=14
14*2=28
14*3=42
we need 28 or 42 pots

Eli walk from her house to a friends house in one hour. She can travel the same Distance on her bicycle in 15 minutes. If she rides 6 mph faster than she can walk, What is her speed on the bicycle?

Answers

Answer: her speed on the bicycle is 8 mph

Step-by-step explanation:

Let x represent the speed at which she walks. If she rides 6 mph faster than she can walk, then the speed at which she rides is (x + 6) mph

Distance = speed × time

Eli walk from her house to a friends house in one hour. This means that the distance covered is 1 × x = x miles.

Distance on her bicycle in 15 minutes. Converting 15 minutes to hours, it becomes 15/60 = 0.25 hour. Distance covered while riding is 0.25(x + 6) = 0.25x + 1.5

Since the distance is the same,then

x = 0.25x + 1.5

x - 0.25x = 1.5

0.75x = 1.5

x = 1.5/0.75

x = 2

her speed on the bicycle is

x + 6 = 2 + 6 = 8 mph

How do you solve (2z-3)(4z-7)=0

Answers

The key to this is to realize that if EITHER quantity in parentheses is zero,
then the whole left side is zero, and the equation is true.

First quantity: (2z-3). If this is zero, then the whole equation is true.

   2z - 3 = 0
Add 3 to each side: 2z    = 3
Divide each side by 2: z = 3/2 or 1.5

Second quantity: (4z-7). If this is zero, then the whole equation is true.

   4z - 7 = 0
Add 7 to each side: 4z    = 7
Divide each side by 4: z = 7/4 or 1.75

So the original equation has two solutions:

   z = 1.5
and
   z = 1.75 .

There are two values of z in this question. (2z - 3)
-3 / 2 = -1.5
-1.5 x -1 = 1.5

(4z - 7)
-7 / 4 = -1.75
-1.75 x -1 = 1.75

z = 1.5 or 1.75

What is 5 1/2% tax on $20?

Answers

5.5 move decimal place over twice 20*.055 =$1.1 in sales tax

5 1/2 percent must be converted to decimal form first to calculate immediately the value of 5 1/2 percent of $20. 5 1/2 percent over 100 percent is equal to 0.055. The product therefore is equal to 0.055*$20 equal to $1.1. The final answer is $1.1. The unit $ remains the same
